Quadratic equations are a key GCSE maths topic. A quadratic equation has the form: ax² + bx + c = 0 There are several ways to solve them. Method 1: Factorising Example: x² + 5x + 6 = 0 Factorise: (x + 2)(x + 3) = 0 So: x = −2 or x = −3 Method 2: Quadratic Formula The quadratic formula is: x = (-b ± √(b² − 4ac)) / 2a This method works for all quadratic equations. Method 3: Completing the Square This method is useful for rewriting expressions and solving equations. It is also useful when...
